PATENT MOSES GREGSON, OF PI-IILOMATH, OREGON.

BOILER-FEEDER.

$IPECIFICA'DION forming part of Letters Patent No. 533,803, datedFebruary 5, 1895.

Application filed April 18, 1894. Serial No. 508,044. (No model.)

To all whom it may concern:

Be it known that I, MOSES GREGSON, of Philomath, in the county of Bentonand State of Oregon, have invented a new and Improved Boiler-Feeder, ofwhich the following is a full, clear, and exact description.'

The object of the invention is to provide a new and improved boilerfeeder, which is simple and durable in construction and arranged tointroduce at regular intervals a measured quantity of water into theboiler, from the supply pipe.

The invention consists of certain parts and details, and combinations ofthe same, as will be fully described hereinafter and then pointed out inthe claims.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a sectional side elevation of the improvement; and Fig. 2 isa plan view of the same.

The boiler A is provided with the feed or supply pipe B,in which isarranged, a suitable distance above the boiler, a casing O, as isplainly shown in Fig. 1, and supported on a suitable framework D. Theupper end of the feed or supply pipe B is connected with the watersupply tank E, so that the water can flow by gravity through the pipe Band its casing G to the boiler A, to fill the same.

In order to regulate the quantity of Water passing from the supply tankE to the boiler A, I provide two valves F and G in the said casing O,the said valves being arranged to alternately open and close, so thatwhen the valve G is closed and the valve F is open, water can flow fromthe tank E into the easing, to fill'the same between the valves F and G,and then the valves are reversed, that is, the valve F is closed and thevalve G is opened, as shown in Fig. 1, to permit the water in the casingto flow through the lower end of the feed or supply pipe 13 into theboiler A.

In order to cause a ready flow of the water from the casing O to theboiler A, I provide the steam pipe H, adapted to connect the bore of thecasing 0, below the valve G, with the valve F, which, for this purpose,is met erably made as a two-way valve, as indicated in Fig. 1, and whenin a closed position it connects with the upper end of the pipe H, sothat steam can flow from the boiler to the supply pipe B into the lowerend of the easing O, and through the pipe H and valve F upon the top ofthe water contained in the casing C, so as to equalize the pressure onthe top and bottom of the water, and to permit the same to flow, by itsown gravity, through the open valve G into the boiler A.

In order to alternately operate the valves '13 and G at statedintervals, the following mechanism is provided: The valve stem F of thevalve F is connected with a pitman I having a slot 1 engaged by a crankarm J formed on a shaft J journaled in suitable hearings on standards Dof the frame D. The shaft J is provided with a pulley K, connected withsuitable machinery for turning the said shaft at a certain rate ofspeed, governed by the amount of water needed for the boiler during acertain length of time. The valve stem G of the other valve G islikewise connected with apitman L having a slotted end L engaged by acrank arm J likewise secured on the shaft J and extending in an oppositedirection to the crank arm J.

When the several parts are in the position shown in Fig. 1, and theshaft J, in rotating in the direction of the arrow a acts by means ofits crank arm J on the pitman L, so as to close the valve G, then theother crank arm passes loosely through the slot I until the crank pin ofthe said crank arm J finally moves against the outer end, so as toexerta pull on the pitman I, to open the valve F. Water can now flowfrom the supply tank E through the upper part of the supply pipe B intothe casing C, to fill the same above the closed valve G. On the furtherrevolving of the shaft J the crank arm J first acts on the pitman L, tomove the valve G- into an open position, and then the crank arm J actson the pitman I, so as to close the valve F by moving it into theposition shown in Fig. 1. Communication is now established between thevalve F and the pipe H with the boiler, to equalize the pressure on thetop and bottom of the water contained in the casing C, so that the waternow flows by its own gravity through the open valve G to the boiler, Theabove described operation is then re out requiring a pump, injector, orother forcing'device.

A marked advantage of the device herein shown and described over priorconstructions of its class is, that water of any temperature may be usedby this device without in any manner interfering with its Working.

Having thus fully described my invention, I claim as new and desire. tosecure by Letters Patent" 1. A boiler feeder, comprising two rotaryvalves arranged in the feed or supply pipe and located suitabledistances apart, thesaid valves being adapted to be turned .to alternately open and close the same, and a steam pipe connecting theuppermost, valve with the supply pipe below the other valve, when saiduppermost valve is closed and said lower valve is open substantially asshown and described.

2. The combination with a casing forming a continuation or section ofthe feed water pipe and provided with a valve at both ends toalternately open and close the respective ends thereof; the upper valvehaving a twoway passage, of a steam pipe extending from the casing belowthe lower valve and communicating at its upper end with the casingthrough the passage in the upper valve when said valve is in its closedposition, substantially as described.-

3. The combination with the casing and its rotary valves having crankarms, the upper valve having a two way passage and a steam pipeextending from the lower end of the casing below the lower valve andcommunicating with the upper part of the casing throughthe two-wayvalve, of an oppositely cranked shaft and pitnlen connecting said crankswith the valve cranks to alternately open and close said valves,substantially as described.
